N18RR

The private pilot accelerated the twin-engine airplane down a 3,000 foot grass airstrip to an indicated airspeed speed of approximately 80 mph when it “suddenly began to rain hard.” Unable to see, the solo pilot attempted to aborted the takeoff roll; however, the airplane exited the airstrip and impacted a mobile home. The airplane came to rest in an upright position and the pilot was able to exit unassisted. The fuselage sustained structural damage during the mishap. The pilot later reported that there were no mechanical failures or malfunctions with the airplane’s flight controls. In addition, the pilot reported that he had not received instruction in the accident airplane make/model, nor did he hold a multi-engine pilot rating at the time of the accident.
